how to listen on both IPv4 and IPv6 adress?

[kobe-koto]

followed #298 but not working.

mtg version v2.1.7

this is my config:

secret = "7v...."
bind-to = ":58964"

I got this

# mtg run /etc/mtg.toml
mtg: error: cannot init config: cannot parse config: cannot parse a config: empty host: :58964

and trying to listen on IPv6 only:

config:

secret = "7v..."
bind-to = "[::]:58964"

*it just runs, no output

and it does listening on IPv6

# netstat -tunlp | grep mtg
tcp6       0      0 :::58964                :::*                    LISTEN      102755/mtg  

and don't know why I cannot connect it through IPv6 but IPv4 works
